I don't think this set complements your original style of Anivers. It has some poetic strokes in it. Basically only letters that are the same in both alphabest hold that. All the others are rather much more geometric. A tweak here an there and I think it could be a nice complement to your Roman set.

Maybe I should also 'break' the pure rectangular shapes...

very nice, voobshche!
a couple concerns:
the body of the Ф is nice and large, but the main stroke endings (top and bottom) are likely to get lost at smaller sizes. this stroke can actually overshoot the cap height line and the baseline and will generally improve the appearance of this glyph.
the arms on ЖКжк seem splayed a bit too much to me. if the diagonals could be a bit more upright, i think these glyphs would look better. the ж looks a bit extra wide in the lower case, but i seem to always make mine too narrow, so it might be just right.
the upper bowl on the я could be a bit larger.

What I mean, of course, it that the letter ё is replaced by a blank in the words создаём and определённые.

oh, i like it, Jos!

i prefer your previous rectangular lc forms, because they have some "wave" a bit corresponding to latin lc. please give more play over them, and more play with center-crossed lowercases like -в-я-з- maybe something like your -a- or -e- forms?

you can make left leg in -л- (and -д-) more flowing, and make diagonal in -и-й- (and even horizontal in -н-) less geometric.

-м- looks unclear for me, -П-п- looks too wide, -У- and -Я- looks too narrow, -б- looks old-timed, -Й-й- be better with a bit bigger breve.

maybe right oval in -ф- will be better if you mirror them? maybe top of oval in -ь- can follow -b-? and you can animate tails in -ц-щ-

sorry for my english and good luck with this beauty!

Jos,
these new letters is better for me.
maybe try you make -д- wider and -л- a bit narrower?
would you make a more flexible ascender in -б- like a leg in -к-ж-?
and please try to mirror a central element in -в-.

and thank you very much for compliments ))

Wow ... great samples Adam! This should make it a bit more easy for me. I'll make the changes soon.

Andreij, I'm thinking of making the bar in -в- straight as is was before. It just doesn't feel right.

I like first б better. I don't particularly like your ж (I guess я and к are still also the problem), it is very weak at the bottom and bold at the top. I think you should entirely redesign the relation between the lower legs and the top parts in ж, я and к (both UC and lc).

I think л and д are not a bit better, though still not balanced enough. The "shelf" in д is still too short — it realy needs to be visible in small sizes. The LEFT edge of the right tooth in д should be located slightly to the RIGHT of the RIGHT edge of the right stem of д. In other words, the right tooth of д should be clearly off limits of the right stem of that letter.

Regards,
Adam
